Specification of Letters Patent.

Application filed May 1, 1913. Serial No. 764,868.

To all whom it may concern:

Be it known that I, J osnrrr HOLLIS, subj ect of George V, King of Great Britain and Ireland, and residing at 1 .St. Paulsproad,

Leicester, England, have invented certain new and useful Improvements in Wood- Irimmers and the like, of which the following is a specification. I I

Thisinvention relates to and the like.

wood-trimmers The object of the invention being to provide means for exposing the unused and sharper edges of the knives in the 7 wood trimmer to the wood to be cut as the cutting which gives clearance for the-knives when they are lowered. A

A further object being to provide means for cutting angles of more than one inclination, (what I term compound angles) as frequently required, for example,by joiners in cutting cornice molds or by pattern'makers in cutting fillets. Now, by thisi-nven tion, I can readilyand accurately "cut the mold at any angle. To do this I take advantage of one of the beveled edges which it is customary to form on the edges of the, molding, by using it to automatically determine the angle at which the molding is to be For use in conjunction with'saidbew cut. eled edges, I provide'a pair of shoes furnished with sliding stops. ing been set to the required angle, and the lower beveled edge of the molding having been brought hard up thereto Ithen bring the. corresponding shoe and stop into contact with the molding so that the upper edge of the latter rests in the angle between the sliding stop and the underside of the shoe, whereupon the molding is ready to be cut.

A further object of this invention is to enable boards, molded skirtings etc., which are of greater width than the vertical capacity of the machine to be. beveled or mitered. To this end the machine is provided with a removable canting orsloping table or frame which is capable of angular; movement and which can be secured at any 1 angle or slope depending upon the angle of The fence havcut required to be made. In using the canting table the board or the like is placed thereon with the end to be cut in the angle between the horizontal table of the machine and the knives.

In using wood-trimmers it has been found Patented June 29, 1915. l

that, other conditions remaining the same,

the same angle of cut is not obtained with hardwood as with soft wood, nor with sharp knives as with dull knives, nor with wood of regular cross-section as with wood of irregular cross-section, this belng due to the varying resistance which the wood offers I to the knives while it is being out. Consequently, when the fence is always set to a given angle (more especially45") the angle of out obtained varies under the different conditions just referred to, with the result that the finished joint between two pieces of molding or the like is defective. Now, according to the present invention, this error inthe angle of cut is compensated for by means ofdevices whereby the fence can be quickly angle.

In order that this invention may be clearly understood and readily carried into effect, I will proceed to describe the same with refer and finely adjusted to the correct ence to the accompanying drawings, wheretive view of a modification in which the stops are formed in one piece. part end elevation of the machine illustrated in Fig. 1 and more clearly shows the gap and the knife carriage. Fig. 6 shows in front elevation a portion of a wood-trimmer with the canting table in position and a piece of stuff lying on the canting table. Fig.7 is an end elevation of the left hand end of Fig. 6. Fig. 8 shows on a smaller scale the canting table in perspective. Fig. 9 is a perspective view of a port on of a, wood-trimmer and shows a stop-pin carry- Fig. 5 is a.

means of set-screws 6, Z) to the rear edge of" the table 0 of the machine. The upper end of the outer limb b of the bracket 'is pro vided with a groove d in which'thelower edge of the knife carriage 6 slides, the upper edge of the knife c'arrlage being arranged to slide in an upper fixed guide is. p A similar bracket is affixed to the opposite end of the table.

The knives shown at c, e, are secured to,

the knife carriage e, e, by means of'screws e e spaced equally apart and it will be seen that as their lower portions become dull or nicked they can be readily lowered into the gap a by removing the screws 6 e and secured in a fresh position by re-inserting the screws 6 6 show the knife lowered into the gap.

Describing now the shoes and sliding stops for holding cornice moldings, etc. in position for cutting, reference will be hadto Figs. 1, 2 and 3, wherein it, h, are the shoes which are provided with upright pins it,

h" and stops 72 7L2, the latter being'lo'ngitudinally adjustable in: slots h it, formed inthe shoes. These are adjusted to height to suit moldings of different depth by sliding their pins 12/, h, in sockets j, 7', projecting forward from the upper fixed guide k of the knife carriage, the pins being held in the sockets by means of thumb-screws j. The usual fence Z having been swung around to the desired angle and fixed in its slot Z in the usual manner, and the lower beveled edge of the molding m having been brought to bear against the fence as shown in Figs/1 and 3, the shoe and stop are ad-- jus-ted to it so that the top edge of the moldingrests in the angle between the shoe and 1 the stopas illustrated. In this position, the

molding is ready for cutting. It will be seen that by swinging both of the fences around to the proper, angle and bringing both of the shoes and their stopsin position both internal and external angles can be out on the moldings.

Sometimes, in carrying out; this invention, instead of making the shoes separate, I may join the pins it, h together by a straight bar provided with a slot from end to end in which to accommodate the stops k Z2? (see Fig. 4) but it is more convenient to have separate shoes, because if only one shoe is being used the other can be raised or" completely removed so as to provide more working space;

The broken lines in Fig. 5

Referring now to Figs. 6, 7 and 8, the canting table therein, show-ncomprises a 'frame .07. capable of angular movement in theangle between the table 0 and the knives e,'e. The outer rail of the canting table extends over. the edge of the fences as illustrated' and'i's provided with bolts 01, n

fwhichpass through slots Z Z withuwhich. the fences are furnished. The bolts carry' fly-nuts n If. The curved edge of the fences is marked with the angles 45, 60

and 67-1 (or other desired angles) and the canting table is secured at the required angle By re by screwing up the fly-nuts n 17?. moving such fly-nuts from their jbolts, the canting table can be at once removed.

Dealing now with Figs. 9, 10and'11, 0 I

isthe 'stop-pinwhich is provided withan adjustable set-screw 0 and with a projecting pin or lug 0 The stoppin is intended to be dropped into one of the holes 0 provided for it in the table'fc and is prevented from turning therein bylits pin or lug o fitting into a recess 0 provided at one side of the hole. In operation the fence may first be set along the required angle line found engraved in the table c, the stop pin isthen droppedinto the corresponding hole 0 and the set-screw 0" is then adjusted sofas-to set vthe'fenc'e at the required angle. The lug Z on thefence is provided with a flat face with 1' whichthe set-screw 0 is maintained in constant engagementowing to thepull of the tension spring 79. The fence having been finally adjusted, the clamping screw q is screwed down tightlyin the usual manner.
